The 702.4a is a hammer for medium heavy jobs, for ornaments structuring etc, with air consumption regulation with a highly sensitive valve control, rotating exhaust silencer and chisel bushings for all common shanks. Two classes of weight are avalaible: the heavy hammers are steadier in the hand, because mass absorbs further vibrations.
